INDEPENDENTLY-DETACHABLE UNDERSHADE FOR LIGHT-STANDARDS.

Application filed A use, 1919.

To all whom it may concern:

l e it known that l, lVTATTI-IEW Y. SUGI- mom, a subject-of the Empire of Japan, and a resident of the city of New Yorlnborough of Manhattan, in the county of New York and State of New York, have invented a new and Improved Independentlymletachable Undershade :t'or Light-Standards, of which the following is a full, clear, and exact description. I i

This invention relates to a new and improved lamp shade and relates more specifically to a shade constructed and adapted to be positioned. below a source of light supported on a standard fixed or portable from below, and relates more particularly to the construction and arrangement of such a shade which is readily adapted to be independently removed or positioned without necessitating the removal or disassembly of the lamp fixtures or other shades or reflectors used therewith. I

A. further object of this invention is to provide an under lamp shade which serves as an indirect light reflector and also softens the direct downward glare from the source of illumination positioned above, and to permit such a shade to be independently removed without disturbing the assembly of the lighting fixtures.

ii inother object of this invention is to pro? vide an independently detachable undershade or reflector which may conveniently be used in combination with other lamp shades suitably positioned with respect to the undershade to produce a shade of a neat and pleasing appearance. This feature is particularly desirable when used with a lamp shade or covering of the ordinary type, which usually is positioned over the source of illumination, leaving the space below the shade subject to the direct glare of the source of illumination. The undershade comprising this invention is particularly adapted to be independently positioned below the source of illumination and the above mentioned lamp shade to either completely or partly cover the space immediately below and within the lower area covered. by the lamp shade first-above mentioned. It is thus seen that the direct glare of the light is thus eliminated and a very pleasing and restful effect is obtained.

While an indirect reflector or undershade is well known in the art when provided with a source of illumination suspended from MATTHEW Y. SUGIMURA, 0F YORK, N. Y. a

above, it is believed to be broadly new to provide a shade of this character to be applied to a source of illumination mounted upon a standard portable or fixed from be low and so constructed, positioned or supported as to be independently removable or detachable without necessitating the removal of other accompanying shades or reflectors or the disassembly Still a further object of this invention is to provide an undershade of the character above-mentioned, which is simple in construction, and which may readily be made of any suitable material including glass, metals or fabric materials.

The above objects are accomplished by providing a shade having an opening in the center thereof adapted to receive a'support or standard extending therethrough, said shade being constructed to permit the insertion of said standard within said open ing by providing an opening or passage for said shade extending from the central opening outwardly or radially, through which the standard or support is moved in bringing it within the central opening, there being provided a means for closing this radially or outwardly extending passage .when the shade has been positioned with respect to the centrally extending support or standard.

A further object is to provide an improved method of positioning and applying an undershade with respect to a source of light supported on a standard from below. This is accomplished by providing a shade having a split centrally disposed opening to receive the standard and a split rim portion.

Other objects and advantages will appear by reterence to the following description and accompanying drawings in which similar of the lighting fixtures.

characters of reference designate like parts substantially complete inclosure for the lower portion of the upper shade.

F 2 is a plan view of a split shade show 7 ing the securing means for the diilt'erent portions. It is through this opening that the standard is passed in order to be positioned within the central opening of the shade.

ing its use in combination with an ordinary lamp shade having its lower edge projectlng nwardly and showing amodified iorm 01' support for the undershade.

Fig. 6 is another modified form of the 'shade shown as comprising a split ring having a suitable connecting means for the ends thereof and suspending cords for positioning the shade-below the source of illumination, there being provided a suitable fabric material connected to the ring and eXtending inwardly toward the center, being there covered and held by a flexible or yielding cord. I c

Fig. 7 is another modified form showing a removable slidable panel extending from the central opening outward so that the standard may be inserted therethrough to be positioned in the central opening, this construction being particularly adapted for shades made of glass, china and the like.

Fig. 8 is a sectional view taken on the line 8 8 of Fig. 7.

Fig.9 is a'modified form or this invention. in which a segment of the shade is removed in order to position thestandard within the opening, there being further shown the annular concentric 7 opening through which the cords may pass. Q Fig. 10 is a sectionalv view taken on the line l0-1 0 looking in the direction of the arrows of Fig. 9 showing the construction ofthe securing means for the joint.

Fig. 11- is anot'her modified form showing a hinged panel portion which may be moved downwardly to form the radially extending passage to the central opening.

Fig. 12 is asectional view taken on the line '1212. looking in the direction or the arrows of Fig. 11.

Fig. 13 is another modified form of the invention showing a segment along one of these radially extending sides.

lNhilc itis old to provide an independ entlyrremovable shade or a reflectorpositioned below a source of light suspended from above, an entirely new problem is pre-j sentedwhen the source of light is supported by a standard or fixture from belowyand attempt then made to provide an undershade or reflector which may be independently removed without requiring the disassembling oi the lighting fixtures or the re moval of other cooperating shades. In addition to requiring anew construction to enable the above result to be accomplished, a new method ofapplying the shade is also used. This consists essentially in the provision of a shade having a split frame constructed to permit the support for the source of light to be passed therethrough to its centrally disposed position with reference to the shade.

In Fig. 1 the 'undershade is shown positioned beneath a source of light, shown herein as comprising incandescent bulbs 1, but it isunderstood that any suitablesource of illumination may be used. The lights are suitably carried on a support 2 from below, there being also provided an upper shade 3 carried at the top of the support 2 by suitable fixtures 4. 7

I The undershade, the preferred form of which is shown in Fig. 2, comprises an outer frame member 5substantially circular in form split at the point 6, there being pro vided at the ends of the member a suitable means for connecting or securing the ends together, herein shown as comprising a spring catch 7 adapted to'engage a notched portion 8 to hold the ends of the split members together when they are engaged, but it is understood that any suitable securing or fastening means may be used. At .a point 9 of the outer frame member approximately diametrically opposite to the split portion, there is connected, preferably by a weld or soldered connection, other members 10 and 11 which extend from this point centrally of the shade and connect at their other ends with the ends of the split frame members 7 at 12 and 12 respectively. There are formed ineach oi? the members 10 and 11 a number of coinciding semi-circular portions 13, 14, 15, 16, 17 and 18, these bent portions forming, when the ends 7, 8 oi the split member 5 are engaged, openings through which the lamp cords 19 and 20 and the standard 2 extend. It is understood, however, that these, bent portions may be of any suitable shape, the essential feature being that there is provided suitable openings in the split passage to receive. the lamp cords and the supporting standard.

As a means of furnishing an additional bracing member there are provided other radially extending members 21 and 22, which connect the two split concentric circular frame members of the shade, the smaller-one being made up of the semi-circular bent portions 15 and 16 and the outer one comprising the'split frame member In thisconstruction it is seen that the point 9 acts as a hinge point about which the sections of the shade are hinged. After the frame structure of the shade has been formed, any suitable covering may then be .member of the shade.

used, such as fabric material, glass, china, etc.

Any suitable means may be used for properly positioning or supporting the undershade below the source of light, the means shown in Figs 1 comprising the cords 23 having one end connected to a suitable fixture carried by. the standard or support 2, there being provided at the other end of the cord 23 a hook 24 adapted to engage the member 5 of the shade to'hold the same in position. It is to be noted that the undershade may be of a suitable size or design to either partly or to substantially completely close the space below the upper shade, and that an nndershade constructed as herein shown and described maybe independently detached or removed without requiring the removal of the upper shade or the disassembly of the lamp fixtures. For example, in order to position the undershade, it is only necessary to disengage the. connection for the split member 5 permitting the shade to be'formed into substantially two sections, in this particular construction connected at the point 9, so that to position the shade. it is carried'below the upper shade 3, the standard 2 is passed through the split portion 6 and the undershade moved until the standard 2 is in alinement with the centrally .ends of the frame member 5 are then drawn together and there connected by the looking or securing means. is placed in its final position, the cords 23 will hang freely in a substantially vertical position, so that the undershade may be held in' a slightly inclined position and the hooks 24 carried at the ends of the cord 23 may successively engage the outer frame It is apparent that to remove the undershade the process is just reversed, this also being done without disturbing either the upper shade or the lamp fixtures.

A modified form of construction is shown in Fig. 3, in which instead of providing spaced openings, such as shown in Figs. 1 and 2, for receiving the lamp cords, there is provided another circular frame member 25 spaced from and substantially concentric with the inner circular frame member formed by the bent portion 15 and 16, thus forming an annular opening 26 through which the lamp cords may pass.

Another modified form is shown in Fig. 4, which shows the undershade as comprising a plurality of sections 27, 28. In such a construction as this as a means of connecting the split portions and holding the shade ,in the proper central position, there are pro- Before the undershade' vided other suitable fastening or connecting meansa-t the, opposite diameter at the points 29 and also at the central'points 30 of the shade. 4

There is shown in Fig. 5 a modified form of construction which may be used to support the under-shade from the standard the device herein shown comprising a clamping band 31 positioned around the support or standard 2, there 'beinga suitable connector 32 having its ends attached respectively to the band 31 and the undershade for the support of the latter. The lamp shade 3 here in shown in this figure as an inwardly and upwardly extending surface 33, which together with the undershade forms a substantially complete closure for the space be low the main upper shade portion.

Another modified form of the shade is shown in. Fig. 6, which comprises a single rim 34 split at the point 35, there being also provided at this point a suitable connecting device. As a means of forming a closure for the area within the rim and to eliminate the necessity for the use of a cumbersome frame structure, this area may be covered by a suitable fabric material 38 having one edge secured to the rim 34 and having the ends of the material extend inwardly from the split point 35 toward the center 36, the edge of the material being here gathered and formed and held in position by the passing of a cord 37 around the edge thereof, it being understood that when the shade is positioned above the support, the rim is split at the point 35, the ends of the cord untied so that the support 2 may be passed through thesplit portion to the center of the shade and within the ends of the cord, so that when properly positioned, the ends of the split rim 34 maybe connected and the ends of the cord 37 may be tightened, thus forming a substantially complete closure from the rim inward. to the supporting standard. It is further understood that any suitable material may be usedto close the. space within the split rim member and the supporting standard.

Another modified'form of the undershade, particularly adapted for the use of glass or china for the covering, is shown in Fig. 7. The radially extending frame members 39 are preferably formed of I-shaped channel members having the'extended flanges 40, whichserve as guides for glass or. porcelain 41, which slidestherein. The inner frame member 42; is splitat the point 43, there being provided a removable'segment 4.4 therefor, which is carried with a removable radially extending sliding portion 45. The outerU-shaped rim frame member of the shade 46 is also split, there being provided a removable section or segment 47 therefor,

'Wl1iCl1.i$ carried at the outer extremity of disposed opening.

the slide 45 so that when the slide 45 is withdrawn, there is formed a radially extending opening through which the support may be passe l in order to be positioned within the central opening 48 of the shade,'

after which the slide 45 is again inserted in its proper position. As a means of holding the slime 45 in position and to prevent the accidental withdrawal of same, there is provided a spring slide 49, shown in Fig. 10 as comprising a thin piece of sheet metal material shown as embracing the outer U-shaped rim member 46, oneside of said spring member bent to form resilient or springing effeet against the rim member'46, the said spring member 49 being moved to embrace the removable segment 47 when properly positioned. i

. A further modifieationis shown in Fig. 9

in which a segment of glass 50 is shown as being removable from the main shade carrying therewith a segment 44 of the inner frame member 42'and also a segment 47 of the outer U-shaped rim frame member'46,

there being provided a'suitable spring slide member 49 whichembraces the split portions of the outer rimmember when the segment is properly positioned. A portion of the inner concentric rim 51'is shown as being removable with the segment, this con- ,struetion facilitating the positioning of the downwardly extending lamp cords.

A modified form, such as that shown in Fig. 11 may be used to eliminate the necessity of having a sliding removablemember to provide a passageway leading fro'mfthe edge of the rim 46 inwardly to theeentrally The construction herein shown'provides a spring hinge connection 52 for the segment 45 which may be moved about thehinged point to permit the insertion of a standard within the central openlng. i r I The construction is more clearly shown in the section shown in Fig. 12, showing the hinged spring connection 52 and the U- .shaped channel 53 adjacent thereto for receiving one edge of the covering material 45,

which may be glass, porcelain or other suitable material, there being provided at the opposite edge a U-shaped frame member 53 having a projecting lip 54 at its upper edge which serves asa rest or support for the movable edge of the hinged segment.

In Fig.1?) there is shown a modification niuchlike that shown in Fig. 9 with the exception that here, also like Fig; llythere is provided a hinged spring connection 55 for the segment 50, which isshown in Fig. 9 as being removable. At the outer movable edge of the segmentrim 47 there is provided a spring catch 56 to hold the hinged segment 50 in position. The preferred form of construction herein shown comprises a sliding rod 57 which engages an split portions.

opening in the hinged segment 50 carried in the housing 58 in which there is provided a slot 59, there being an upwardly extending finger member 60 connected'with the sliding rod 57, there being further provided spring 61 within the housing 58 to force the sliding rod outward.

Suitable openings are shown in Figs. 7 11 and 12 through which the lamp cords may extend.

It is un lerstood that changes and modifications may be made without departing from the spirit and scope of this inventionl H avingthus described the invention, what I claim as new is:

cluding connectors extendingfromthe outer concentric frame member to the supporting standard, one end of the connectors being detachably fastened to the undershade,

whereby the said un'dershade may be independently positioned without requiring the removal or disassembly of the lighting fixtures or the .u'ppershade.

-' 21' An undershade adapted to be independently positioned below a source of light shade having an opening in the center thereof to receive the supporting standard and a split metal rim for said shade forming a passageway communicating with the central opening through which passage the support may be passed and a means connecting the standard and the outeredge of the .undershade to hold it in the proper position, one end-of said means being detaehably connected to the rim of the shade whereby the undershademay' be independently positioned without requiring the removal of the source of light.

.3. An undershadecomprising a plurality of split substantially concentric metallic frame members, arc-like radially'extending bracing members rigidly connecting said split portions and a means at the'end of the concentric members for connecting said 4. The combination of a supporting standard, a plurality of electric lightin d fixtures carried at the upper part thereof,

"supported on a standard from below, said lll an uppershade supported on said standard, a split undershade, and means connecting the outer periphery of said split undershade with the standard whereby the undershade may be independently positioned Without requiring the removal of the electric lighting fixtures and the uppershade.

The combination of a supporting standard, lighting fixtures including a plurality of electric lights carried at the upper part of said support, an uppersliade or reflector for said lights, and a split undershade supported on the standard, the said undershade being adapted to be independently positioned Without necessitating the removal of th upper shade and lighting fixtures, the said undershade having a plurality of parts, each part comprising an outer semi circular frame, radially extending are like members connecting the ends oi the semi circular frame, the said are like member having a bent portion intermediate the ends and forming an opening adapted to receive the standard when the two parts are in assembled position.
